Frankly I am at a loss here. This happened because I committed something
from my ecpg_big_bison branch. But it went into HEAD again. The tags
simply were lost on my directory. I have no clue at all how this could
happen.
BTW the actual preproc.y file does compile fine with bison 1.49, but
then ecpg gives me syntax errors where none should be. After removing some 30k
of rules from the bison file ecpg works as it should. Maybe this is just
another bison bug.
